Exported video has black bars all around

Ho everyone, i have a problem.

usually when i export videos the only bug that simethimes happens is the audio missing thing, but this time i don't know hwta i touched, but the video is zoommed out and there is black screen all around.

Do you have any idea on what setting i might have touched?
Or how to make sure the black bars are not there?
